Burner for a combustion device

Abstract

A mixer has its associated fuel gas nozzle inserted on one side and includes an inlet section for introducing combustion air via a gap defined therearound to allow it with a fuel and a jetting outlet section for jetting a resultant air/fuel mixture. A cylinder is fixed to the jetting outlet section to burn the mixture. A burner head is fixed to the cylinder to allow the mixture which is jetted from the jetting outlet section via diffusion holes to be guided into the cylinder.

What is claimed is: 
     
       1. A burner for a combustion device, comprising: a fuel gas nozzle for supplying a fuel gas;   a mixer into which the fuel gas nozzle is inserted on one side and including an inlet section for introducing combustion air via a gap defined therearound to mix a fuel gas with the combustion air in the mixer;   a jetting outlet section integrally projected on the other side of the mixer and having jetting holes for jetting the fuel gas and combustion air which are mixed in the mixer;   a cylinder fixed to the jetting outlet section, having a substantially rectangular open end and adapted to allow the mixture to be burned; and   a burner head fixed to the cylinder and including diffusion holes for diffusing the mixture which is jetted from the jetting holes.   
     
     
       2. A burner according to claim 1, wherein said inlet section of said mixer allows an incoming fuel gas to, together with said combustion air, collide against an opposite wall surface of the mixer so that both are directed toward the jetting holes in a direction perpendicular to a direction in which they are introduced. 
     
     
       3. A burner according to claim 1, wherein said jetting outlet section of said mixer is projected with its vertical dimension reduced to allow said mixture to be jetted via said jetting holes after being rectified. 
     
     
       4. A burner according to claim 1, wherein said cylinder circumferentially takes in secondary air and having secondary flame holes for forming a flame pattern. 
     
     
       5. A burner according to claim 1, wherein said burner head has a rectangular opening initially. connected to an associated opening of said cylinder with said jetting, outlet section extending therein. 
     
     
       6. A burner according to claim 1, wherein said burner has an outer face opposite to the jetting holes of said jetting outlet section projected inwardly along a longitudinal direction. 
     
     
       7. A burner according to claim 1, wherein said diffusion holes are provided at a predetermined interval at those upper and lower corners of said burner head to allow said mixture to be diffused at a predetermined angle toward the wall of said cylinder. 
     
     
       8. A burner for a combustion device, comprising: a fuel gas nozzle for supplying a fuel gas;   a mixer into which the fuel gas nozzle is inserted on one side and including an inlet section for introducing combustion air via a gap defined therearound to mix it with a fuel gas;   a jetting outlet section integrally projected on the other side of the mixer and having jetting holes for jetting the fuel gas and combustion air which are mixed in the mixer;   a fixing plate fitted around the jetting outlet section;   a cylinder fixed to the fixing plate and having a substantially rectangular opening and adapted to allow the mixture to be formed; and   a burner fixed fixed to the cylinder and including diffusion holes for diffusing the mixture which is jetted from the jetting holes.   
     
     
       9. A burner according to claim 8, wherein said fixing plate comprises a fixing section fixed to said jetting outlet section, an attaching section integrally bent along the end of the jetting outlet section in a direction perpendicular to that in which the fixing section is fixed to the jetting outlet section, and a section integrally bent in the same direction as that in which the fixing section is fixed to the jetting outlet section. 
     
     
       10. A burner according to claim 8, wherein said cylinder has a flange formed at an open end and fixed to said fixing plate.
